One pet peeve that gets to me is something that’s done on a lot of commuter railways and S-Bahns, the 10/20 minute schedule. The schedule looks like:
2:10
2:20
2:40
2:50
3:10
etc, when it should be like this:
2:10
2:25
2:40
2:55
3:10
This minimizes waiting and allows for frequent service every 15 minutes.
What are your pet peeves?
Massive train/metro station platforms with just a couple of benches and a small fraction of it covered. Most people have to wait in the rain / baking sun.
Buses / trains not running at night.
On-level pedestrian crossings of railroads with ridiculously loud “incoming train” bells
